| 摘 要： | 阵列天线是指由多个离散的辐射元,按一定规律排列组成的天线系统.其具有高增益,强方向性,主瓣可控等特性.文中研究了利用切比雪夫法对阵列天线输入不同参数:馈源单元数N,馈源间距d,副瓣电平SLL,得出参数改变对阵列天线方向图的综合影响,通过工程示例论证出切比雪夫法用于方向图综合的优缺点.为切比雪夫法用于天线方向图综合比较提供了一种有效的参考方法.

| Abstract: | The array antenna is a system consisting of some discrete radiation members arrayed by a certain rule.It has the characteristics of high gain,strong directivity,and controllable main lobe.This paper studies and utilizes the principle of Chebyshev by inputting different parameters to the array antenna,including the number of feed source units,the space between feed sources and the level of the minor lobe and discovers the effect of the change in parameter on the directivity pattern.It also shows the advantag... |
